This problem and its solution follow the patterns illustrated in the Actor 4 example. It also extends the class relationship problem presented at the end of the previous chapter. The problem establishes the variable names (class members and function parameters), and they must be used consistently by your solutions.
class Person
{
private:
string name;
public:
Person(string n) : name(n) {}
friend ostream& operator<<(ostream& out, Person& me)
{
out << me.name << endl;
return out;
}
};
class Project
{
private:
char code;
public:
Project(char c) : code(c) {}
friend ostream& operator<<(ostream& out, Project& me)
{
out << me.code << endl;
return out;
}
};
class Record
{
private:
double salary;
public:
Record(double s) : salary(s) {}
friend ostream& operator<<(ostream& out, Record& me)
{
out << me.salary << endl;
return out;
}
}
class Employee : public Person // Inheritance
{
private:
Record myRecord; // Composition
Project* myProject = nullptr; // Aggregation
int id;
public:
Employee(string name, double s, int i)
: Person(name), myRecord(s), id(i) {}
friend ostream& operator<<(ostream& out, Employee& me)
{
(a)___________________________________
(b)___________________________________
(c)___________________________________
(d)___________________________________
return out;
}
};
Fill in the blanks to complete the Employee inserter function.
